Question

What is the measure of angle A?

Answer 1

angle a + 15° + 38° = 180° [ Linear pair]

a + 53° = 180°

`a = 180 - 53 \\ a = 127`

So, a = 127°

Answer 2

a = 127

Explanation:

These angles are supplementary which means they add up to 180:

15 + a + 38 = 180

a + 53 = 180

a = 180 - 53

a = 127
